PT is 3 days a week with the entire battalion to do a workout of some type. Class is about leadership and values/ideas the Army wants from you (warrior ethos, UCMJ, Army values, officership, etc.) and lab is hands on "training". This semester in lab we learned about combat first aid, how to properly use radios, land nav, assembly/disassembly of weapons, as well as a few other skills. MSIs and MSIIs have basic lab where we learn simple skills like I just described. MSIIIs have advanced lab where they learn things like maneuvers, lanes, and other advanced skills. The MSIVs taught the labs with cadres help.
